Find the value of in the triangle shown below.
2.5
2
6.5
I have attached the complete question with the triangle.
Answer:
x = 6
Step-by-step explanation:
From the image attached we are told to find x in the triangle.
The triangle is a right angle triangle and so we can use pythagoras theorem to find x.
x² = 6.5² - 2.5²
x² = 42.25 - 6.25
x = √36
x = 6
Sydney read 50 5050 pages in 40 4040 minutes. She reads at a constant rate. How many pages can Sydney read per minute?
Answer:
1.25 or [tex]1\frac{1}{4}[/tex] pages per minute
Step-by-step explanation:
We are to determine the speed at which Sydney reads
Speed = total pages red / total minutes
50 / 40
The above fraction can be expressed its simplest form by dividing the numerator and the denominator by 10
5 / 4
the above fraction can be expressed as a mixed fraction as [tex]1\frac{1}{4}[/tex] or as a decimal as 1.25 pages per minute

The surface area of a cube can be found using the formula S = 6e. If a cube
has an edge of 3.5, what is the surface area of the cube?
Answer:
S = 73.5 unit³
Step-by-step explanation:
[tex]A_{s} = 6e^{2}[/tex]
[tex]A_{s} = 6 (3.5)^{2}[/tex]
[tex]A_{s} = 6 (12.25)[/tex]
[tex]A_{s} = 73.5[/tex]
Answer:
73.5 unit^2.
Step-by-step explanation:
Area = e^2
Area of one face = 3.5^2 = 12.25 unit^2.
So total surface area = 6 * 12.25
= 73.5 unit^2.

Which of the following questions describes the equation g + (-4) = -5?
What number, when subtracted from negative five, is equal to negative four?
What number, when added to negative five, is equal to negative four?
What number, when added to negative four, is equal to negative five?
What number, when subtracted from negative four, is equal to negative five?
Answer: What number, when added to negative four is equal to negative five.
Step-by-step explanation:
Rearange the numbers to get -4+g=-5.
This eqation now reads -4 plus a number g is equal to -5, and can also be read as what number (g) added to -4 = -5.
If we were to solve for g we would get g= -1.
Answer:
the third option, "what number, when added to negative four, is equal to negative five?"
Explanation:
"what number, when added to negative four, is equal to negative five?" can be expressed as g + (- 4) = - 5, which is the same as in the equation.

Determine whether the conclusion is valid. Explain.
You want to determine the number of students in your school who have visited a science museum. You survey 50 students at random. Twenty have visited a science museum, and thirty have not. So, you conclude that 40% of the students in your school have visited a science museum.
A. yes; The sample is representative of the population, selected at random, and large enough to provide accurate data. So, the sample is unbiased and the conclusion is valid.
B. yes; The sample is representative of a specific group, selected based on age, and small enough to provide accurate data. So, the sample is biased and the conclusion is valid.
C. no; The sample is not representative of the population because students who are older have had more opportunities to visit a science museum. So, the sample is biased and the conclusion is not valid.
D. no; The sample is representative of the population, selected at random, and too large. So, the sample is unbiased and the conclusion is not valid

Rico spins the spinner twice and determines the sums of the spins. Fill in the sample space to determine the possible outcomes. What is the probability that Rico will get a sum less than or equal to 8? A 13\frac{1}{3} 3 1 B 23\frac{2}{3} 3 2 C 89\frac{8}{9} 9 8 D 59\frac{5}{9} 9 5
Answer:
2/3
Step-by-step explanation:
Sample space for the sum of 2 spins :
Number on spinner = 2, 5, 4
____ 2 ___ 5 _____4
2___ 4 ___ 7 _____ 6
|
5___ 7 ___ 10 ____ 9
|
4___ 6 ___ 9 ____ 8
Hence,
(4, 7, 6, 7, 10, 9, 6, 9, 8)
Probability of getting a sum less than or equal to 8;
Probability = required outcome / Total possible outcomes
Required outcome =, sum ≤ 8 = 6
Total possible outcomes = 9
P(sum ≤ 8) = 6/9 = 2/3

Find x and TU
Show all the work
Answer:
x = 10
TU = 24
Step-by-step explanation:
To find the value of x, we use the trapezoid mid-segment theorem
The sum of the lengths of the two parallel sides is equal to twice the length of the mid segment
Mathematically, we have this as;
2(2x+ 4) = 2x-4 + 3x + 2
4x + 8 = 5x - 2
5x -4x = 8 + 2
x = 10
TU = 2x + 4 ; = 2(10) + 4 = 20 + 4 = 24

Debra and Alexandria can finish a plowing job in two hours if they work together. Debra can do the job in 7 hours by herself. How long would it take Alexandria to finish the same job alone?
Answer:
2 hours 48 minutes
Step-by-step explanation:
Debra=1 plowing job / 7 hours
Debra+Alexandra=1 plowing job / 2 hours
1/2-1/7
=7/14-2/14
=5/14
=1/14/5 (Alexandra can do 1 unit of plowing job per 14/5 hours)
14/5 hour=2 hours 48 minutes (hope hits helps)
Alexandria to finish the same job alone in, 2 hours 48 minutes
What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
Debra and Alexandria can finish a plowing job in two hours if they work together.
And, Debra can do the job in 7 hours by herself.
Hence, We get;
For Debra = 1 plowing job / 7 hours
Debra + Alexandra = 1 plowing job / 2 hours
Hence, Time to take Alexandria to finish the same job alone is,
= 1/2 - 1/7
= 7/14 - 2/14
= 5/14
= 1/14/5 (Alexandra can do 1 unit of plowing job per 14/5 hours)
= 2 hours 48 minutes
Thus, Alexandria to finish the same job alone in, 2 hours 48 minutes

Two sides of a triangle have lengths 7 and 15. Which inequality represents the possible lengths for the third side , x?
Answer:
8 < x <22
Step-by-step explanation:
In this question we know the two sides of the triangle to be 7 and 15, let's all the other side x
One one side of the inequality we have:
7+15>x
22 > x
On the other side we have
7 + x > 15
X > 15-7
X>8
When we rearrange these inequalities above we have
8<X<22
We saw from the calculations that 8 is less than X and X is less than 22.
